Specific embodiment
1-4 and specific embodiment are described in further detail the utility model with reference to the accompanying drawing.
Vertical screw agitating mill as shown in Figs 1-4 mainly includes cylinder 1, cover 2, spiral agitator and motor
7, the top of cylinder 1 is equipped with overflow port 8, and lower part is equipped with inlet pipe 9 and accident thick liquid discharge mouth 12, and cover 2 is dismountable by bolt
It is connected to the top of cylinder 1, the helical blade 4 that spiral agitator is fixedly connected on main shaft 3 by main shaft 3 and helical form forms,
Main shaft 3 protrudes into 1 bottom of cylinder after passing through bung 2 from top to bottom, and the output shaft of motor 7 drives main shaft 3 in cylinder 1 by belt pulley
Inner rotation, and cylinder corrugated liner 6 is fixedly connected on the inner wall of cylinder 1, it is fixedly connected on the upper surface of helical blade 4
There are helical blade corrugated liner 5, cylinder corrugated liner 6 and the corrugated structure distribution of helical blade corrugated liner 5.
In addition, being also connected with high pressure washing water pipe 10 on inlet pipe 9, high pressure washing water pipe 10 is equipped with controlled valve,
Discoid bottom Support tray 11 is welded on the bottom end of main shaft 3,11 vertical distribution of bottom Support tray in 3 bottom end of main shaft, and
The distance between bottom Support tray 11 and grinding machine bottom, that is, 1 bottom end of cylinder are 2d, and wherein d is milling medium (steel ball, porcelain ball)
Maximum gauge, the bottom end of main shaft 3 is fixedly connected on by bottom Support tray 11, and bottom Support tray 11 and cylinder are between 1 bottom end
Ore pulp and milling medium (steel ball, porcelain ball etc.), are not only able to play a supporting role, can also reduce in 3 rotation process of main shaft
The abrasion of main shaft 3.
Wherein, cylinder corrugated liner 6 is distributed along 1 inner wall of cylinder, and helical blade 4 can be as shown in figure 3, only upper surface be solid
Surely it is connected with helical blade corrugated liner 5, it, can also be as shown in figure 4, helical-blade of course for crush and grind effect is further increased
The upper and lower surface of piece 4 is fixedly connected to helical blade corrugated liner 5.
Grinding machine working principle is as follows:
In the agitating auger operation process of low speed rotation, since the effect of centrifugal force, gravity, frictional force causes crushing medium
Realize that the motion cycle of orderly fashion and stress macroscopically are in a basic balance with material, for less than promotion speed in agitating auger
Material spiral escalation, material between 4 outer rim of cylinder corrugated liner 6 and helical blade is spiral decline, cylinder wave
Line liner plate 6 and helical blade corrugated liner 5 make milling medium be formed on its surface micro- cast and decline movement, and high-pressure washing water accelerates ore grinding
The classification of material, increase grinding efficiency, however, microcosmic on due to its discontinuity formed dynamically move speed difference, by
Power variation causes material to be fractureed by the stress between strength extruding, grinding and material, ultra small scale manufacture, split the comprehensive functions such as broken, closes
